Dear R People:

I need to set up an lme. I have logratio as my response var, range, and I(range^2) as the fixed variables.

The random effects vars are xa1 through xa24.

How do I set up the lme statement, please?

I tried with
lme(logratio ~ range + I(range^2), random=fmla)

is an as.formula statement with the xa1 throught xa24 var with a leading

Any suggestions, please

Thanks,
Erin Hodgess
